Removal & Installation



C-Clip Type
  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Remove or disconnect the following:

    Wheels
     
    Brake rotors
     
    Driveshaft
     

  4.  
  5. Check the bearing preload with an inch lb. torque wrench.
  6.  
  7. Remove the pinion flange and seal.
  8.  

To install:


NOTE
Use a new pinion nut for assembly.

  1. Install the new pinion seal and flange. Tighten the nut to 210 ft. lbs. (285 Nm).
  2.  
  3. Check the bearing preload. The bearing preload should be equal to the reading taken earlier, plus 5 inch lbs.
  4.  
  5. If the preload torque is low, tighten the pinion nut in 5 inch lb. increments until the torque value is reached. Do not exceed 350 ft. lbs. (474 Nm) pinion nut torque.
  6.  
  7. If the pinion bearing preload torque cannot be attained at maximum pinion nut torque, replace the collapsible spacer.
  8.  
  9. Install or connect the following:

    Driveshaft
     
    Brake rotors
     
    Wheels
     

  10.  
  11. Fill the axle assembly with gear oil and check for leaks.
  12.  

Non C-Clip Type
  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Remove or disconnect the following:

    Wheels
     
    Brake rotors or drums
     
    Driveshaft
     

  4.  
  5. Check the bearing preload with an inch lb. torque wrench.
  6.  
  7. Remove the pinion flange and seal.
  8.  

To install:


NOTE
Use a new pinion nut for assembly.

  1. Install the new pinion seal, flange and new pinion nut.
  2.  
  3. Check the bearing preload. The bearing preload should be equal to the reading taken earlier, plus 5 inch lbs.
  4.  
  5. If the preload torque is low, tighten the pinion nut in 5 inch lb. increments until the torque value is reached. Do not exceed 260 ft. lbs. (353 Nm) pinion nut torque.
    NOTE
    For 302RBI axles the pinion nut should be tightened to 689 ft. lbs. (937 Nm) with a torque multiplier (and torque wrench.

  6.  
  7. If the pinion bearing preload torque can not be attained at maximum pinion nut torque, remove one or more pinion preload shims.
  8.  
  9. Install or connect the following:

    Driveshaft
     
    Brake rotors or drums
     
    Wheels
     

  10.  
  11. Fill the axle assembly with gear oil and check for leaks.
